I guess in the long run it'd be better to get my last pair of IEM's as my first and get some nice expensive ones.. but then again... it's a lot of money. and most people will buy entry levels or top of the line... don't see many people buying mid level. The most id think of spending as a first set of IEM's would be like 750 or so. For 750 I think I can get the sensaphonic 2max's (that my favorite band killswitch engage uses live!) but I'd buy the version of the 2max's that are made more for cable use because apparently the 2max's are optimized for use with wireless systems.

The Sensaphonics 2X-S ($750) and 2MAX ($850) have identical sound signatures. They are essentially dfferentiated by their sensitivity.

In touring sound, artists expressed a need for more sensitivity when using wireless monitor systems, so Sensaphonics developed the 2MAX in response. That's what they mean by"optimized for use with wireless systems."

The relevance to home/portable audiophile listening is a question of your sound source and listening habits.
